Hi there ~
I understand your concerns and that you have been suffering from multiple issues for a long period of time, that can take a toll on both you mental and physical health. I am glad that you are under treatment for a lot of conditions and hope that you are better with all the medical issues that you mention. I also think that you may need to go for MRI
of neck CT of PNS and Chest X-ray if your doctor has been recommended. I believe that you will need to visit a doctor in any case.
I hope this helps. Take care and have a lovely day!
